ODORLESS EXCAVATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 231,827, dated August31, 1880. Application filed June 21, 1879.

.To all whom it may concern:

Be it known that I, ALFRED W. J. MASON, a resident of the city of NewOrleans, parish of Orleans, and State of Louisiana, have in vented acertain new and useful Improvement in Odorless Apparatus for .OleaningPrivy- Vaults; and I do hereby declare the following to be a full,clear, and correct description of the same, reference being had to theannexed drawing, making a part of this specification.

This invention relates to odorless apparatus or means for cleaningprivy-vaults; and the novelty consists of an air-tight elevator, incombination with a receiving-tank and deodorizer.

The object of this improvement is to do away with the expensiveair-pumps now employed in this system, and substitute in lieu thereof aportable air-tight elevator which shall be simple and cheap inconstruction.

On the drawing, A is intended to represent a privy-vault, B an air-tightelevator, C a receiving-tank, and D a deodorizing-vessel.

The elevator B, like others of its class, has its casing composed of twotubes, to b, the ends of which are connected, as at c 01. I11 these endsare fitted, upon shafts c f, suitable drums, over which operates anendless band, G, the latter provided with a number of elevatingbuckets,as at h.

The lower end of the casing isleft open and provided with a screen, I,and over the same is secured, after each operation, an air-ti ht cap, L,so as to effectually exclude all smell at the said point during theremoval or transportation of the same. The dischageopening at the upperend of the casing should also be provided with a detachable cap for alike purpose.

The tank 0 is furnished at one side wit-h a gage, i, to exhibit thequantity of matter therein, and the deodorizer is provided with aremovable cover, 70, to admit of a furnace being placed thereupon. Thetank 0 is connected for operation with the upper end of the elevator anddeodorizer by means of pipes l and on.

To operate the invention, first removethe air-tight cap L from the lowerend of the elevator, then sink the said end \Vllll its screen into theprivy-vault, nextremove the cap from the upper end of the casing, andmake the pipe-connections between the elevator, tank, and (leodorizer.Remove the cover from the latter vessel, and place in lieu of same afurnace with lighted charcoal or other fuel therein. The machine is"then put-into operation by turning the cranks of the elevator in thedirection indicated by the arrows.

The gage on the receiving-tank will show when to stop the apparatus, andthe fire in the furnace wtll destroy all gases passing into thedeodorizer.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is-

l. The elevator B, composed of tubes (1. b, united at their ends, buthaving the lower end reticulated, and the endless band G, provided witha series of buckets passing over drums arranged on the shafts cf,substantially as set forth.-

2., In an apparatus of the odorless class, the elevator B, provided withan endless band, Gr, carrying a series of buckets, and having the lowerend which enters the vault reticulated and provided with the air-tightcap L, covering the said reticulated portion of the elevator,substantially as described.

3. An odorless excavating apparatus consisting of the elevator B,carrying a plurality of elevating-buckets, and having its lower endreticulated, a connectingpipe, Z, receivingtank 0, with transparentgage, connectingpipe m, and a deodorizer, D, substantially as shown andset forth.

In testimony whereof I have hereunto signed my name.

ALFRED WV. J. MASON.
